Re: ATL: TWO - Potential Tropical Cyclone - Discussion
At this point this has gained enough organization to be declared a TS. Looks like SA helped tighten it up

Re: ATL: TWO - Potential Tropical Cyclone - Discussion
Strong waves often produce TS winds on the north side when moving >20kts to the west. I saw that little swirl near the coast of Venezuela at first light, but does it qualify for an organized LLC? I'd say no. Meanwhile Caracas has a NW wind at 10 kts and the ABC islands are at 10-15 kts from the NE-ENE.

I think its cool to see land friction due to Venezuela, don't see that often. This is clearly a weak TS at this point. So much for the "NHC overnames everything" conspiracy theory

290 deg wind is not a true NW wind, is more westerly than NW.

Re: ATL: TWO - Potential Tropical Cyclone - Discussion
Hopefully recon can get a little further south to confirm with extra certainty that an LLC has formed. I’m not sure if the NHC will be comfortable upgrading it to TS Bonnie just yet.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Re: ATL: TWO - Potential Tropical Cyclone - Discussion
Naked swirl alert on visible, looks like a closed llc to me. Not exactly strong, but if it can maintain or reform further into the convection I think it’ll make quick work of the open waters once it clears SA

West wind 5 kts at Caracas, east wind 10 kts at Bonaire. Raining at Curacao & Aruba with 5-10 kt winds. Heaviest squalls are 200 miles north of the weak swirl. Hardly qualifies as a TS. Good radar from Accuweather:

Recon went back, too bad, that naked LLC is now getting into Dutch air territory.

What they did get might be enough. Look at how the wind barbs shifted as they traveled along 12.5N above the naked swirl.

That wind shift just indicates a wave axis, not a circulation. That naked swirl was nothing.

Time will tell, that naked LLC is going straight for Curacao or will at least track very close to the south of it.

Re: ATL: TWO - Potential Tropical Cyclone - Discussion
On satellite, it looks more like a wave than it has for 2 days. The MLC is no longer evident.

Something that it didn't have during the past couple of days, a closed weak circulation. IMO.

It looks like the rotation that was near to the coast earlier if moving more north west pulling away from the coast and would be going over Bonaire about now.

Re: ATL: TWO - Potential Tropical Cyclone - Discussion
Just a naked swirl. NHC's discussion agreed with me - less organized and more elongated. It'll get its LLC tomorrow evening after passing Colombia.

Re: ATL: TWO - Potential Tropical Cyclone - Discussion
Dmax is coming in several hours and could be enough to keep the circulation intact, or maybe tighten it up a bit before it finally starts pulling away from Colombia tomorrow.
The 5pm NHC forecast now calls for a hurricane in the EPac. Watch this be a low end C1 at landfall in the Atlantic and blow up into an EPac major to copy some other July storm from 96.

Actually it's Dmin that is coming in several hours. Dmax is 10+ hours away
